KERUI SISJW01 Water Leak Detector 5 Pack: POWEFUL 90dB ALARM: Emits a loud 90dB alarm once water is detected, easily heard even in large rooms or noisy environments for early warning to prevent costly water damage
This 5-pack of water leak detectors is for the homeowner who wants simple, reliable protection against hidden leaks. Think of it as your first line of defense for under-sink cabinets, behind the washing machine, or in that damp basement corner where a small drip could turn into a major headache.
While many focus on high-tech smart home integration, these detectors offer something different: instant, no-fuss peace of mind. You don't need Wi-Fi or an app—just place them and forget them. The 90dB alarm is loud enough to cut through household noise, so you'll hear it from another room before water spreads. The included extension cables let you snake a sensor into tight spots, like behind the toilet or under a pipe joint, catching leaks where they often start unseen.
Each unit runs on batteries for easy placement anywhere, with low power consumption for long-lasting monitoring. It's a practical set-and-forget solution that works quietly in the background, giving you one less thing to worry about in your daily routine.
